- Tag environment or scene images as background and characters or objects as subject for the most accurate compositing.
- Use clear, well-lit reference images with distinct subjects for the best identity preservation.
- Use 360p to rapidly test your scene composition before committing to a higher-resolution render.
- Enable audio for scenes with strong ambient environments like outdoor settings, crowds, or action sequences.
Notes
- Both prompt and images are required fields; all other parameters are optional.
- Each image entry must include image_url, type, and ref_name.
